VETERINARY NARGOTIG INJEGTOR.

TOALL WHOM. IT MAY CON OERN Be it known that I, MORITZ CROHN, of thecity and county of St. Louis, and State of Missouri, have invented a newand useful Narcotic Injector for Veterinary Purposes; and I do herebydeclare that :the following lis a full and clear description'thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.` i

In this invention a common smoking pipe may be used, the said pipe beingprovided iwith a cover 4to the bowl, from the top of which there is aflexible tube, the outer end of which is terminated in a rigid nozzlesuitable foi' injecting purposes. At the base of the bowl or stem of thepipe there isol small bellows, by means 0i' which airis forced `throughthe burning narcotic, in the pipe-bowl, to the injecting pipe.

The object of this invention is to produce a cheap and convenientinstrument, whereby the smoke of some burning narcotic may be injectedinto the mouth or rectum of animals, for the cure of certain diseases inwhich such treatment has been or may be found beneficial.

l To enable those skilled in the art. to make and usevmy improvednarcotic injector, I will proceed to describe its construction andoperation.

The drawings represent the improved instrument in elevation.

`A is the bowl .ofa common smoking pipe, which isprovided with a cap, a,from the apex of'which there is a. flexible tube, B, the said tube beingconnected by means of the coupling b with a nozzle, B', of some hardmaterial, such as is commonly used forsyringes. In the drawings, thecoupling'b is show-nin section, so Vas to disclose the 'arrangement forattaching .theI nozzle yto the end orthe side of the 'said coupling, asmay be most convenient atthe time ofusing. A cap, is usedto cover upthe'orice notused by the nozzle B. At the base ofthe bowl there is a.stem, C, of wood, or some other non-conducting material, and to the endof this stem vis attached a bellows or India-rubber bulb, C. Y A portionof the back end of this bulb is broken out in the drawings, so as todisclose the small Hap-valve @,aiiixed to the inner end ofthe base-pluge', which is :perforated to admit air to the bulb. By alternatelypressing and relaxing the bulb C air is'drawn into it through the vulvec, and expelled through the bowl A and nozzle B. l

Having described my invention, what I claim is- The combination andarrangement of therbowl A, the tube B B', and the bellows C c,substantially as and for the purpose set forth.

In testimony of which invention I hereunto set my hand in presence oi`MORITZ CROIIN.
